As I get older I'm more and more comfortable being alone.

The only real progress lies in learning to be wrong all alone.

If you are lonely when you're alone, you are in bad company.

Unless we love and are loved, each of us is alone, each of us is deeply lonely.

All of our unhappiness comes from our inability to be alone.

Alone we can do so little together we can do so much.

Every man must do two things alone he must do his own believing and his own dying.

It's often just enough to be with someone. I don't need to touch them. Not even talk. A feeling passes between you both. You're not alone.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.
